Stringers assembled at a circumferential joint of an airplane fuselage

Abstract

The disclosed embodiments relate to an airplane fuselage produced by assembling, at a circumferential joint, at least two sections including a skin and at least one stringer split into two elements and which are assembled at the joint between the two sections by at least one splicing plate. The splicing plate includes a web having a bearing surface including two surfaces bearing on lateral faces of the elements of the stringer, the two surfaces being offset by an amount ε substantially equal to an error of alignment between the lateral faces of the elements of the stringer.

1. An airplane comprising:
 a fuselage having at least first and second sections connected at a circumferential joint wherein each of the sections comprise a skin and at least one stringer, the stringers extending parallel to a longitudinal axis of the fuselage, each of the stringers further comprising: 
 a lateral surface, wherein, in the assembled position, the lateral surface of the stringer of the first section is out of alignment with the lateral surface of the stringer of the second section at the joint, by an alignment error ε; 
 at least one splicing plate constructed to connect the stringers at the joint of said first and second sections, the splicing plate further comprising: 
 a web having a first bearing surface bearing on the lateral face of the stringer of the first section and a second bearing surface bearing on the lateral face of the stringer of the second section, wherein the first and second bearing surface of the splicing plate web are connected by an inclined plane that is constructed to offset the first bearing surface from the second bearing surface by a distance ε substantially equal to the error of alignment between the lateral faces of the stringers. 
 
     
     
       2. The airplane fuselage according to  claim 1 , in which the stringer is fixed to the skin of the fuselage. 
     
     
       3. The airplane according to  claim 2 , in which the stringer is fixed to the fuselage by rivets. 
     
     
       4. The airplane according to  claim 2 , in which the stringer is a-fixed to the fuselage by welding. 
     
     
       5. The airplane according to  claim 2 , in which the stringer is fixed to the fuselage by bonding. 
     
     
       6. The airplane according to  claim 1 , in which the web of the splicing plate comprises a flat surface on the opposite side to the bearing surface. 
     
     
       7. The airplane according to  claim 1 , in which the web of the splicing plate is of constant thickness.
